Abstract: In one embodiment, a method comprises identifying, by an apparatus, a mesh instability source device that adds a substantial instability influence that substantially degrades network communications in a mesh network, including: determining, for each mesh network device in the mesh network, a corresponding node stability contribution that identifies a long-term capability of the corresponding mesh network device to provide reliable communications for other mesh network devices in the mesh network, and determining a corresponding influence of the node stability contribution on child mesh network devices relying on the corresponding mesh network device for connectivity in the mesh network, and identifying the mesh instability source device as having a corresponding worst influence of the node stability contribution in the mesh network; and eliminating the substantial instability influence based on determining a remediation solution, and causing the remediation solution to be implemented for the mesh instability source device.

Abstract: In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.

Abstract: In one embodiment, a controller predicts an occurrence of an event in a wireless network, based in part on a movement of a mobile node of the wireless network. The controller initiates application of network-layer forward error correction encoding to a stream of packets to be sent during the event between the mobile node and an access point of the wireless network, to form one or more encoded packets. The controller causes the one or more encoded packets to be transmitted in conjunction with the stream of packets during the event. The controller ceases application of the network-layer forward error correction encoding after the event has occurred.

Abstract: In one embodiment, a client device having a plurality of radios obtains a list of basic service set identifiers (BSSIDs) for a plurality of wireless access points of a wireless network. The client device associates each of the plurality of radios of the client device with a different wireless access point of the wireless network, based on the obtained list of BSSIDs. The client device receives a copy of a data packet from a particular one of the associated wireless access points. Each of the associated wireless access points receives a replicated copy of the data packet to be transmitted towards the client device. The device causes the associated wireless access points to cease further transmission of their copies of the data packet by acknowledging receipt of the data packet to the particular wireless access point.

Abstract: In some embodiments, a device in a network receives a packet from a sender that is destined for a receiver. The device forms duplicate packets of the packet. The device assigns a sequence number to the duplicate packets based on an identity of the sender and on a flow identifier associated with the packet. The device sends the duplicate packets with the sequence number via different paths in the network towards the receiver.
